I do not know where to start but Xcode 9 is a total mess, with countless bugs and performance issues.
I myself reported 7 bugs so far, and there are many more to report. But I gave up.
Why did I give up? Because I started to feel Apple does not care about us, the Developer Community, at all.
For Apple, the Developer Community is nothing more than some impressive numbers to be stated in their fancy Keynotes and blog posts.
Xcode 9 is a joke, it should not have been released at all.
Actually, it is worse than a joke, it is an insult.
Tens of thousands of developers working hard to make apps and giving life to the App Store ecosystem.
But nowadays, most of them are busy with dealing ridiculous Xcode 9 problems, instead of working on their own products.
Why? Because some people at Apple are so dedicated to ruin existing products, instead of improving them.
They choose to spend their time, money and energy on making useless stuff and creating more problems.
And they feel no shame about releasing underdeveloped and undertested products.
Apple's software quality is constantly degrading, especially last few years.
I am sure I am not the only one who can see this fact.
Along with iOS, any Apple operating system, web service or other kind of software product have unacceptable amount of problems.
From the end user viewpoint, these might be simple problems they encounter occasionally. Maybe they do not notice at all.
But from the developers viewpoint, this is serious. This is making our jobs less funny and more painful, as well as costing us time and money constantly.
Today, Apple is one of the most succesful companies in the world.
Anyone in the business clearly knows, Apple would not be at this point without iPhone.
And iPhone would be nothing without the App Store, and the App Store would be nothing without the Developer Community.
So, we want our voices to be heard.
We want people at Apple to know that they are failing their jobs and we are getting sick of this.
People at Apple!
Please show some respect to the Developer Community, and start fixing things without creating more problems.
Stop biting off more than you could chew. Develop more elaborately, and do more comprehensive testing on products before you release them.
